Issue #, if available:

Description of changes:

• Adding support for different schema registry types (Confluent and Glue)
• Improving the handling of message indices in protobuf data
• Fixing deserialization logic for different schema registry formats
• Adding appropriate tests for both Confluent and Glue schema registry scenarios

Schema Registry Type Detection and Deserialization Logic:

No Schema Registry Integration:

• When KafkaEvent contains no key/value metadata
• Uses entire byte array as raw data for deserialization
• AWS Glue Schema Registry:

Identified by 16-byte schema ID in key/value metadata

• Skips first byte of data
• Uses remaining bytes for Protobuf deserialization
• Confluent Schema Registry:

Default case when neither of above conditions are met

• Follows Confluent wire format specification
• Dynamically skips 1 or 2 bytes based on message index
• Uses remaining bytes for Protobuf deserialization
